Pacinian corpuscles - Study guides, Class notes & Summaries

Abducens (VI) - motor origin: pons term: lateral rectus -rotates eye laterally Accommodation - looking at an object up close -eyes converge ex) crossing -pupils constrict -lens changes: more curved (up close) Adaption of sensory receptors - most sensory receptors adapt, become less sensitive during prolonged time; Nociceptors and most proprioreceptors do not adapt Adrenergic neurons - secrete NE sympathetic postganglionic fibers 1. alpha adrenergenic: constrict blood vessels and dila...

1. layers of skin: 1. Epidermis 2. Dermis 3. Hypodermis (subcutaneous layer) 2. function of skin: 1. absorb UV light for vitamin D production 2. sensory receptors and glands 3. protection from temp. changes 4. protect from miroorganisms 3. sensory organs: 1. merkel cells 2. missener's corpuscles 3. nociceptors 4. thermoreceptors 5. pacinian corpuscles 4. merkel cells: mechanoreceptors detect mechanical sensory information of light touch superficial - epidermis 5. meissener's c...

MN 551 Patho Exam Study Guide Which of the following factors is most responsible for the fact that prefrontal lobotomy is no longer a common treatment for mental illness? - Individuals treated by lobotomy have difficulty interpreting somatic, visual, and auditory information. Lobotomy inhibits the individual's ability to add perception and meaning to sensory information. ******Severing connections between the brain and its prefrontal areas inhibits problem solving and results in a l...

The integumentary system is comprised of what three parts of the body? - Answer Hair, skin, and nails List the three layers of the skin from superficial to deep. - Answer Epidermis, Dermis, Hypodermis Describe three functions of the integumentary system. - Answer Production of vitamin D; contain sense organs for protection of skin and underlying tissue; protection from pathogens True or false: Thermoreceptors detect fine touch. - Answer False Merkel's cells and Meisn...
